CURB INLET.

Application filed September This invention relates to sewer terminal` fittings.

This invention has utility when incorpo rated in pavement grating and curb hood storm sewer structures.

Referring to the drawings:

Fig. 1 is a fragmentary plan view of a pavement showing an embodiment of the invention incorporated therewith at the curb line; Y

Fig. 2 is a side elevation of the storm sewer curb inlet assembly;

Fig. 3 is a plan view of the inlet fram-e;

Fig. 4 is a medial vertical section through the inlet'on the line IWT-1V, Fig. 1; and

Fig. 5 is a section on the line V-V, Fig. 2 looking in the direction of the arrow.

Pavement 1 is shown as extending to curb 2 and having in the pavement extent frame 3, 4, 5, uprising from base flange 6. This frame 3,4, 5, extends laterally outside the pavement region and into the curb region with the sides 3, 5, having lower portions andv cut-oif corners 7, 8, connected by rear side 9. Disposed in this portion of the frame 3, 4, 5, as within the extent of the pavement 1, is member 1() having openings 11 therein providing a grating. This member lO has an additional opening`12. Bolt 13 through this opening 12 engages lug 14 carried by the frame side 4 in assembling this grating to rest on additional lugs 15 carried by the framevsides 3, 5. There is left a region of frame eXtent within the curb line 2, which frame in such region is in the plane of the pavement or below the top surface of the adjacent pavement. This feature is of practical value, especially in present day type of cast-in-situ curbs, for the placing of the forms for such casting operation may be continuous past a sewer inlet. There accordingly need not be interference in placing this inlet as to the curb. The curb may be so left as to provide for the disposal of the inlet completion structure or hood or such may be formed in the curb independently of detracting from the operation of the curb cast for there are no projecting parts above the pavement line to interfere with the curb setting.

The completion of the assembly of the inlet is eected by the placing of hood 16 in position. In so doing, the back 17 of the hood is disposed to rest upon the side 9 with its portions 18, 19, resting upon the frame s, 1925. sei-iai No. 54,215.

porti-ons 7, and Adjacent the rearward side of the grating 10 this hood 16 has dej pending iiange 20 between side flanges 21 at the forward edges of the hood depending portions 19. Thesel flanges 21 terminate in notches 22 astride the frame adjacent the inner ends of the sides 3, 5, to intertit there with. The hood back 17 has lug 23 on the inner side of the frame side 9. The hood depending portions 18 have downwardly extending lugs 24 on the outer sides of the frame side 7, 8. Accordingly, while the notches 22 interfit with the frame sides 3, 5, the lugs 23, 24, provide additional yinterlocking means between the hood depending portions and the frame -snugly holding the hood in deiiniteassembled relation with the frame which assembly may be maintained by anchoring bolts 25.

In this type of structure, under the heavy traliic conditions to which pavement is subjected today, there is occasion of much abuse of such sewer inlet. These abuses arise by concussion-against the hood 16 even to the extent of fracture thereof. In such instances replacement of the hood may be readu ily accomplished independently of apply ing a new frame. Likewise, if the grating should give away such may be replaced independently of supplying a new frame, and the construction of the hood is such that the lug interlocking relation is weaker than the frame 3 and the hood will give way instead of destroying such frame. These are features of simplicity in installation and economy in upkeep for these storm water receiving sewers on pavements or drives. The frame, as built into the pavement, is the part requiring pavement openin to replace, and the up-keep of the breaka le portions thus avoid such trouble in replacement. f

What is claimed and it is desired to secure by United States Letters Patent is 1. A frame having a supporting iange, said frame rising from said flange to have a flat top, a hood uprising from said frame over a portion thereof having a fiat support ing face resting on the frame fia-t top, and lugs from said hood projecting below said frame top and against the frame sides.

2. A frame having a supporting flange, said frame rising from said flange to have a flat top, and a hood uprising from said frame over a portion thereof having a flat loo stress less than the frame, said lugs being disposed alternately Von opposite sides of said frame, said hood also having integral therewith a pair of depending fork portions astiide opposite sides oi' said -frame for' positioning said hood against side movement as to the frame. l Y
